Why
use a HANFLO™ Strain Relief Union? |
 |
The
HANFLO™ Union allows for easy disconnect
and reconnection of equipment. Water pumps, pressure
tanks, pipelines and other products can be easily
removed and easily reinstalled for servicing. |
| |
|
|
What
is unique about a "Strain Relief" Union? |
|
The
Union has a 9-degree "knuckle" type ball
socket allowing for flexibility within the fitting
body, which compensates for slight interface variables
when connecting pipes. An example would be the
interface between black polyethylene pipe and a
water pump. The poly pipe retains some memory (radius)
from the warm manufacturing process as it is coiled.
The strain relief union compensates for this pipe
radius as it is connected to the pump. |
| |
|
|
What
types of pipe can the HANFLO™ Strain
Relief Union connect to? |
|
The
threaded end component of the union interfaces with
any metal or plastic pipe or fitting with NPT (National
Pipe Threads). The poly end component of the union
is specific to interface with CSA grade 75 PSI or
CSA grade 100 PSI polyethylene. |
| |
|
|
Can
the Strain Relief Union be used on suction lines? |
|
Yes,
the HANFLO™ Strain Relief Union can be used
on pressure and suction lines. Like all Hanflo
products the Strain Relief Union is constructed
of glass fibre reinforced nylon, for both strength
and durability. |
| |
|
|
Can
the Strain Relief Union be re-used? |
|
Yes,
the union fitting is designed for this purpose and
can be connected and re-connected time after time. |
| |
|
|
Should
I seal the threads? |
|
You
may use a thread sealant or Teflon tape when threading
any of our HANFLO™ fittings. |
| |
|
|
Is
the Strain Relief Union compatible with all of
the HANFLO™ range of threaded fittings? |
|
Yes,
the entire range of HANFLO™ fittings are
compatible with the Strain Relief Union and the
close tolerance NPT threads (National Pipe Thread)
will ensure a positive and reliable fit. |
| |
|
|
How
do I know which Strain Relief Union I need, poly
or threaded? |
|
The
threaded union is generally used to provide a quick
disconnect at the pump or anywhere a threaded fitting
is used. The poly union provides quick disconnect
where there are two poly pipes interface, for example
at the water’s edge to remove and reinstall
water lines for the season. |
| |
|
|
How
do I size the Strain Relief Union to suit my
application? |
|
The
threaded Strain Relief Union may be sized based
on the existing pipe NPT threads (National Pipe
Thread) you’re connecting to. The poly Strain
Relief Union may be sized based on the existing
polyethylene pipe you are connecting to. The poly
union is specific to CSA 75 PSI and CSA 100 PSI
pipe. |

|
What temperature can I use HANFLO™ fittings at? |
|
HANFLO™ have tested all its products for use with cold water up to a maximum temperature of 60°C (140°F). We do not recommend the use of these products with temperatures higher than 60°C (140°F) as plastic expands due to temperature increases. HANFLO™ can not guarantee the products will perform when used with temperatures over 60°C (140°F). HANFLO™ products that have failed in temperatures higher then 60°C (140°F) will not be covered by warranty. |
